Choose your flavour and combine yogurt and seeds in a bowl. If you are making both flavours, use 2 bowls.
Line a cookie sheet with parchment paper and spread the yogurt mixture evenly. If you are making both flavours use a larger cookie sheet and keep vanilla mix on one side and strawberry mix on the other.
Top with your toppings of choice (fresh or frozen blueberries, granola, almond butter and choc chips).
Set in freezer for about 2 hours. Once bark is set - break into pieces and place in a freezer safe container and enjoy when you want!
